SPECIFICATION forming part of Letters Patent No. 786,162, dated March28, 1905.

Application filed August 3, 1900. Serial No. 25,827.

.upward movement, if desired, said trough being supported upon suitableantifriction devices and rotated in any convenientmanner.

It further consists of novel details of construction, all as will behereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a plan view of a dyeing and saturating machineembodying my inven- Fig. 2 represents a vertical sectional view of Fig.1, certain portions thereof being shown in elevation. Fig. 3 representsa detail view showing the manner of supporting the tub or trough at itscenter, the devices seen in Fig. 3 being omitted from Fig. 2 for Yclearness of illustration.

Similar numerals of reference indicate corresponding parts in the gures.

Referring to the drawings, l designates a dyeing and saturating machine,consisting of the annular tub or trough 2, which is formed l by theinner and outer walls 3 and 4, respectively, and the base portion 5,which in practice preferably inclines outwardly, substantially asillustrated in Fig. 2.

6 designates a central plate which is provided with the bearings 7,adapted to rest in the seat or socket 8, whereby the central portion ofthe machine is supported, the outer portion of the trough havingattached thereto the ring 9, which is adapted to travel upon theantifriction-rollers or similar devices 10, which are preferably conicalin shape, the under surface of said ring 9 conforming to the contour ofsaid antifriction devices.

11 designates a rack, which is suitably secured to the trough 2 and isadaptedv to be in mesh with the pinion 12, to which power may beimparted in any suitable manner, as by the shaft 13 and pulley 14.

15 designates uprights of a frame or housing, said uprights beinglocated oppositely to each other and having slots or bearings 16therein, in which are mounted the extremities 17 of the shaft 18, thelatter having the rollers 19 rotatably mounted thereon, which may beslightly conical and are adapted to freely revolve in the.annular trough2, said rollers being prevented from longitudinal'displacement by meansof the collars 20, and by the contact with the Walls 3 and 4. The endsof the shaft 18 normally rest in the lower ends of the slots or bearings16, and when in this position the rollers 19 are held above the bottomof the tub or trough, as shown in Fig. 2. This construction allows thegoods that are placed in the tub or trough to pass under said rollers,whereas if said rollers rest on the bottom of the trough the goods arepiled up against the same and seriously affect its operation. Moreoverwhen the rollers rest upon the bottom of the trough they are apt toinjure and macerate the goods, especially when the machine contains onlya small quantity.

The operation is as follows: Through the medium of the pinion 12 andrack 11 rotation is imparted to the annular trough 2, the latter beingsupported during its movement and the friction thereof reduced to aminimum by reason of the antifriction devices 10. The

goods to be dyed and-saturated are placed inV the trough, which has beenpreviously filled with the liquor, and it will be apparent that rollersbeing curved to correspond with the curved inner periphery of thejuxtaposed wall 4 of the trough 2.

In case the rollers 19 encounter a large quantity of goods to besaturated the same can rise, due to the fact that the ends of the shaft18 are capable of vertical movement in their 100 bearings 16 and thatnormally the lower periphery of the rollers 19 is a short distance abovethe bottom of the trough 2, as will be understood from Fig. 2.

It will be apparent that other means may be employed for impartingrotation tothe trough 2 than that shown and that other changes may bemade by those skilled in the art which may come within the scope of myinvention, and I do not, therefore, desire to be limited in everyinstance to the exact construction I have herein shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a dyeing and saturating apparatus, an annular trough, the basethereof inclining downwardly and outwardly, a shaft mounted above saidtrough and capable of movement relative thereto, rollers loosely mountedon said shaft and having their outer ends curved to correspond with thecontour of said trough, said shaft being supported to normally hold therollers above and separated from the bottoln of said trough, a rackattached to the bottom of the latter, a pinion engaging said rack, aring secured to said trough, rollers or antifriction devices adapted tocoact with said ring, a central plate secured to theinner wall of saidtrough, a pin depending` from said plate and a seat or socket for thereception of said pin.

2. In a dyeing and saturating apparatus, an annular trough, a shaftmounted above said trough and capable of movement relative thereto,rollers loosely mounted on said shaft, and having their outer endscurved to correspond to the contour of said trough, said shaft beingsupported to normally hold the rollers above and separated from thebottom of said trough, a rack attached to the bottom of the latter, apinion engaging said rack, a ring secured to said trough, rollers orantifriction devices adapted to coaet with said ring, and a centralpivot for rotatably supporting said trough.

3. A dyeing or saturating apparatus comprising a trough, a roller, meansfor positively supporting said roller out of contact with the bottom ofsaid trough and means for giving said trough and said roller relativerotary motion about the axis of said trough.

4. A dyeing or saturating apparatus comprising a rotatable trough, aroller in said trough and means for positively supporting said rollerout of contact with the bottom of said trough.

5. A dyeing or saturating apparatus comprising a trough, a roller, meansfor positively supporting said roller out of contact with the bottom ofsaid trough, means for increasing the distance between said roller andthe bottom of said trough and means for giving said trough and roller arelative rotary motion about the axis of said trough.
